Reference
Bibliography and sources
Every primary source the site draws on, cited in full. Each entry says plainly what the source is used for and, where it matters, how its wording is changed before it reaches a page. Each has its own anchor, so a footnote or a book can link straight to it.
The site works from the editions below. Where a first edition and a working reprint differ, both are noted. Claims are attributed on the pages that use them; this page is the single place their sources are cited in full.
- The Complete Book of Numerology. Hay House, Carlsbad, California, 1992.Pythagorean
The source of truth for the Pythagorean material: the single-digit meanings, the three planes, the arrows across the birth-date grid, and the reduction rules. Where a plane page names an arrow, the label is Phillips’s.
How it is usedPhillips writes in a confident, self-help register. The site keeps his structure and keeps his labels, but rewords his more predictive passages into descriptive pattern language before shipping them.
- Cheiro's Book of Numbers. London Publishing Company (first edition); the site works from later Herbert Jenkins and Arco printings, 1926.Chaldean
The source for the Chaldean material: the older sound-based letter table and the compound-number meanings behind the two-digit readings on the name pages.
How it is usedCheiro’s original readings are fatalistic, written as fixed predictions of fortune and misfortune. The site never ships them in that form. Every compound meaning is rewritten as descriptive pattern language, and the fatalism is dropped, not softened.
- Chaldean Numerology for Beginners. Llewellyn Publications, Woodbury, Minnesota (ISBN 9780738726243), 2011.Chaldean
The modern Chaldean reference alongside Cheiro: the sound-based letter table and the accessible single-number readings behind the name pages. Where Cheiro supplies the older compound meanings, Lagan supplies the contemporary voice.
How it is usedA present-day beginner’s guide, used for the letter table and the plain single-number descriptions. As with Cheiro, any predictive framing is reworded into descriptive pattern language before it reaches a page.
- Numerology Guidance Cards. Hay House, Carlsbad, California, 2013.Angel numbers (moment-reading register)
The thematic reference for the angel-number pages, where a noticed sequence is read as a present-moment prompt. Buchanan informs the themes only.
How it is usedUsed for register and theme, not for wording. The Buchanan material is kept strictly separate from the Cheiro compound meanings; angel numbers are moment-readings, not birth or name numbers, and the site does not cross-wire the two.
- The Destiny Matrix method. Originating work; the method is documented across the practitioner literature rather than a single canonical volume, 2006.Destiny Matrix (syncretic: tarot, kabbalah, numerology)
The originator of the Destiny Matrix system used throughout the /matrix section. This is a separate 2006 syncretic system, held behind a strict firewall from the Pythagorean and Chaldean material.
How it is usedThe Matrix is not Pythagorean numerology and the site never presents it as such. Its arcana are tarot-derived and its structure is its own. Where the tradition uses charged language such as karmic or destiny, the site names those as the tradition’s words and gives the plainer working reading alongside.
- Man and His Symbols. Aldus Books, London; Doubleday, New York, 1964.Depth psychology (framing, not a numerology source)
The source for the site’s framing of why a noticed number can feel meaningful. Jung’s idea of synchronicity, a meaningful coincidence, is how the site explains the pull of an angel number without claiming the number caused anything.
How it is usedJung is a framing reference, not an endorsement of numerology. Citing him explains a psychological effect; it does not argue that the systems are true.
